Water Filtration Services in Amherst, New Hampshire

Amherst is a classic southern New Hampshire town with a historic village center, rolling farmland, and a heavy reliance on private wells. Most homes outside the village draw water from drilled bedrock wells that tap into the same granite formations running under Bedford and Milford. That geology shapes nearly every water concern homeowners here run into. We cover Amherst from our Hooksett shop and know the neighborhoods off Route 101 and Boston Post Road well.

What Amherst homes tend to deal with.

Southern NH

Amherst sits squarely in the southern NH granite belt. The bedrock here naturally contains arsenic, uranium, and radon, and NHDES has flagged this part of Hillsborough County as a higher-risk zone for arsenic in private well water. Homes off Route 122, Mont Vernon Road, and the back roads toward Milford often test above the EPA action level of 10 parts per billion for arsenic without the owner ever tasting or smelling anything wrong. Radon in water is the other quiet one here: the same bedrock that gives you radon in the basement can push radon into your tap water through the well. We also see iron and manganese staining in wells with shallower casings, especially in lower-lying areas near the Souhegan River. PFAS is less documented in Amherst than in Merrimack next door, but the town's proximity to that plume makes baseline testing a smart move for anyone on a private well. Hardness from calcium and magnesium is common across town and is usually the first thing homeowners notice through scale on fixtures and cloudy glassware.

What we install here.

Because arsenic and radon are the headline risks in Amherst, most of our installs here start with a certified arsenic test and, when warranted, a point-of-entry arsenic removal system paired with radon aeration. Whole-home well water systems are the norm rather than the exception. Reverse osmosis at the kitchen sink handles final polishing for drinking and cooking. Water softeners address the hardness that comes with bedrock water. Free on-site testing is the right first step for any Amherst homeowner who hasn't tested in the last two years.
